FO UNTAIN-SYRINGE.

SPECIFICATION forming part of Letters Patent No. 718,202, dated January13, 1903.

Application filed September 9, 1902. Serial No. 122,655. (No model.)

To all whom it may concern:

Be it known that I, JAMES HARDMAN, J r., a citizen of the United States,residing at Belleville, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in Fountain-Syringes;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompa-' nying drawings, and to figures of reference markedthereon, which form a part of this specification.

The present invention has reference to improvements in fountain-syringeswhich are generally suspended from a nail driven into the wall or otherplace. In the use of this class of syringes as now ordinarily made theperson after the use of the syringe usually hangs up the conveying tubeor hose by placing the nozzle into the mouth or neck of the bag orreservoir. This, however, is a very objectionable feature, for its usecauses the flexible tubing to kink, thereby gradually wearing orweakening the tubing or hose at the point where it is placed over theedge of the mouth or neck of the bag or reservoir. To avoid this seriousobjection is the principal object of the present invention, and withthis in view the main purpose of the inventionis to provide the deliverytube or hose of the fountain-syringe with a means of suspension adaptedto be arranged over the edge of the mouth or neck of the bag orreservoir, whereby when the tube or hose is hung up it is constantlykept straight and any kinking of the tube or hose is positively avoided.

A further object of this invention is to provide a novel means in theform of a compression-clamp for compressing the flexible tubing or hose,and thereby shutting off the flow of the liquid through the said tubingor hose.

Myinvention therefore consists in the novel means of suspension to beemployed with the flexible tubing or hose of a fountain-syringe by meansof which the kinking of the tubing or hose is entirely avoided.

withthe flexible tubing or hose of a fountain-syringe by means of whichthe tubing or hose may be compressed and the flow of the liquidtherethrough entirely shut oif.

The invention consists, furthermore, in the various novel combinationsof the devices and arrangements of parts, as well as in the details ofthe construction of the same, all of which will be hereinafter moreparticularly specified and then finally embodied in the clauses of theclaim which are appended to and form a part of :this specification.

The invention is clearly illustrated in the accompanying drawings, inwhich- Figure lis a side view of a suspended fountain-syringe,illustrating the tubing or hose provided with a combined shut-oif orcompression-clamp and a suspension device arranged over the rim or edgeof the bag or reservoir of the fountain-syringe. Fig. 2 is a transversesectional representation, on alarge scale, of the upper portion of thebag or reservoir and the-said combined shut-01f or compression-clamp andsuspension devicewith the nozzle portion of the tubing or 'hose inelevation in its suspended position in said device. Fig. 3 is aperspective view of the said combined shut-ofi or compression-clamp andsuspension device. Fig.4 is a face view of the upper portion of the bagor reservoir and nozzle portion of the tubing or hose, illustrat,

ing a modified construction of suspensionhook independent of the shut-0For compression-clamp; and Fig. 5 is a perspective View of the suspensiondevice represented in said Fig. 4. Fig. 6 is a view similarto thatrepresented in said Fig. 4:, but illustrating still another modifiedconstruction of suspension device, the hook in'this casebeing attacheddirectly to the sideof the bag or reservoir and the nozzle portion ofthe tubing or hose being provided with a ringadapted to be placed overthe said hook.

. Similar characters of reference are employed in all the saidhereinabove-described views to indicate corresponding parts.

In thesaid drawings the reference char acter 1 indicates the usualflexible bag. or reservoir of a fountain-syringe. 2 is the surroundingedge or rim of the mouth or neck of the said bag or reservoir, and 3represents the usual loop by means of which the bag or reservoir issuspended from a nail 4 or other supporting means upon the wall orotherlike place. Connected with the outlet 5 of the said bag orreservoir 1 is the usual flexible tubing or hose 6, which is provided atits free end with a nozzle 7 of any Well-known construction.

Referring now to Figs. 1, 2, and 3 of the drawings, the combinedshut-off or compression-clamp and suspension device in indicated by thereference character 8, and the same consists, essentially, of a backplate 9, provided at the top with a hook or other suitably-arrangedsupporting means 10, adapted to be placed over the edge or rim 2 of thesaid bag or reservoir 1, as shown in Figs. 1 and 2 of the drawings. Theopposite and lowerportion of the said back plate 9 is bent, as at 11,and extending in an upward direction from said bent part 11 isaspring-tongne 12. The said bent part 11 is also made with an opening13, into and through which the nozzle end of the tubing or .hose 6 isdrawn and located between the opposite faces of the said back plate 9and the spring-tongue 12, as shown. The said back plate 9 is also madewith a pair of outwardly-extending ears or lugs 14, arranged at theopposite edges of the said spring-tongue 12 and having their perforatedportions 15 projecting beyond the outer face of the said spring-tongue12. Pivotally arranged between these perforated portions 15 is aclamping-lever 16, provided with a clamping-jaw 17, arranged at anangle, preferably a right angle, to the said lever 16, as shown. Thisjaw 17 rests directly upon the outer. face of the said spring-tongue 12,and when the lever 16 is turned in a downward direction then said jaw 17forces the said spring-tongue 12 directly against the flexible tubing orhose 6 by the compression of the tubing, shutting off the flow of theliquid through the tubing or hose, as will be clearly understood.

Instead of providing the back plate 9 with a hook 10, as in Figs. 1, 2,and 3, the suspension device and the shut-0E or compressionclamp may bemade separate, as indicated in Figs. 4 and 5, in which case a collar orband 18 is secured at the desired place upon the flexible tubing 0rhose, the said collar or band 18 being provided with a book 19, whichcan be arranged over the edge or rim 2 of the mouth or neck of the bagor reservoir 1, as illustrated in said Fig. 4. If desired, a hook 20 maybe secured directly upon the side of the bag or reservoir 1, asrepresented in Fig. 6, in this case being provided with a collar or band21, having an eye 22, to whichis secured a ring 23, adapted to be placedover the said hook 20 when the nozzle portion of the tube or hose 6 isto be arranged in its suspended position.

From the above description of my invention it will be seen that I havedevised a simple device for retaining the nozzle portion of the flexibletubing or hose of a fountain-syringe in its raised and suspendedposition at the side of the bag or reservoir at or near the rim or edgewhich surrounds the mouth or neck of the bag or at any other desirablepart of the bag without any danger of kinking the tubing or hose,whereby the latter is often weakened and rendered useless in a shorttime, and, furthermore, I have provided an easily-operated shut-off orcompression-clamp for readily shutting off the flow of the liquidthrough the said tubing, the said suspension device being used eitherwith or Without the said shut-off or compression-clamp, as may bedesired.

I am aware that changes may be made in the arrangements and combinationsof the devices and the parts thereof without departing from the scope ofmy invention. Hence I do not limit my invention to the exactarrangements and combinations of. the devices and their parts asdescribed in the present specification and as illustrated in theaccompanying drawings, nor do I confine myself to the details of theconstruction of the parts thereof.
